I seem to remember that police chase into Hollywood as well but I couldn't quite remember the circumstances as to why they were chasing him. Other articles stated that Yvette worked at the Dept of Children and Family Services. What Yvette and her ex-boyfriend were fighting about is unknown. But here's a quote from the Glendale News Press:

"After meeting at a club, Hakopian and Grigoryan began their three-month long relationship, which relatives described as tumultuous.

According to County Jail records, Grigor Grigoryan, a 41-year-old white man, remains incarcerated at Twin Towers Correctional Facility in downtown Los Angeles on a $1.24 million bail. He also has an immigration hold on his case, records show. Grigoryan was arrested May 30, 2008.

I love yvette with all my heart, she was an angel who got murdered by a sick animal. I pray every day that this baster will get his punishment . I am waiting more than 2 years for his trial court to begin but they extend it every month.

Yvette was one of the kindest and devotted humans. Loved her family and friends and having such kind heart she was fooled and chased by that monster. Now that his bloody trial is over they should throw away the key and let him be rotten in the jail.

I am Yvette's cousine and the truma that we all been through is indiscribable and the pain is gonna be always in our hearts I miss her a lot. -Anahid Asiun July 19, 2011 @ 16:50

Yvette was my life and I have been loving her like crazy. That baster not only killed Yvette but he killed me too, without her my life is nothing and my eyes are not without tear any more. I am asking God every day to give that animal the suffering that he deserves. I am Yvette's aunt, and I will always love her like crazy.

It's been years and there is not a day that goes by that I don't think about her. She was truely one of the kindest people that I ever met in my life. She had a heart of Gold, so carrying and always there for family and friends with a smile on her face. I've known Evette from Toll Jr. High since 7th grade. She didn't deserve to go that way (know one does) and I hope that bastard rots in Hell. He has the rest of his life to think about what he did to that poor innocent girl and what he took away from the rest of us. Christine T
